This brings us to the final example, the triangle network from Section 3.3. Unlike the previous examples, this case does not have a sequence of measurements, but rather takes all three measurements to occur at once. A number of open questions remain concerning the precise distinction between triangle-network correlations and traditional Bell-correlations [1]}, [2]}, but it is clear that the triangle-network allows for a new sort of no-go theorem without requiring different settings for different runs of the experiment.
